Nice and strong. I'd get better shoes, first of all. It's hard to maintain the bar path in squishy shoes. On the squat itself, you're not getting your back angle set from the beginning. Watch your descent: you don't change back angle at all for the first few inches, and then you have to catch up and set it later, which means that your knees slide into the bottom.
The whole thing is a little disjointed. Three things happen at the same time at the beginning of the squat: chest down, hips back, knees out. Get this right and you'll clear up lots of troubles.
You are also lifting your head and changing your gaze point on the way up. Keep your face pointed 4 or 5 feet in front of you and don't move it. You don't need to lift your head to go up.
You've got a pretty wide grip with your wrists bent under the barbell. I'd like to stretch you out and get that narrower, so that you have a better and tighter thoracic spine.
I'd sure like a more solid setup. Have you considered upgrading the rack?
Deadlift looks ok except that it's really a block pull.
